They'll look fine...I just went to my locall BB and i set the kit lens (24-85mm VR) on crop mode (mind you this is an FX lens) and believe it or not, IQ was fine.. I wouldnt worry to much about it..I was atonished at the IQ of the D600 in DX mode..My D7k and 16-85MM VR have been placed for sale and will be replaced by this fine camera.
